Summoned skeletons get stuck in district corners, invisible walls and in other mobs. And it isn’t possible to summon them again. It creates huge problems. I don’t see it possible to play Necromancer further. So far the situation won’t be corrected.
Thes is also happen in dungeins.
For example in 240 lv Blue Fortress Dungeon
When you teleport to final boss you lose all of your pets and can not resummon skeletons.
Each time when you use a suspended cabin for movement. Skeletons are also lost. And it isn’t possible to summon them second time on the fact that they are still living on the other side. And you can’t change chenal in dungeons to resummon.
Thanks for attention. Excuse for my English it is not my native language.
